2.93V threshold — the rail it watches
The TPS3838K33DRVR is a single-channel voltage supervisor from TI's TPS3838 family, monitoring a 2.93V threshold with an active-low, open-drain reset output. This threshold targets 3.3V nominal rails — it asserts reset when the supply drops below 2.93V and holds it low for a minimum 10 ms timeout after the rail recovers.
The 6-WSON package is a common footprint across TI's supervisor line, so a pin-compatible alternate within the TPS3838 family (different threshold voltage) is a straightforward swap if the monitored rail changes.
